所以我使用.的说明在Ubuntu上安装了sbt,但是当我在终端执行sbt时,由于“没有找到可信证书”,我得到了下载失败的错误.我做得不多,所以我不确定我做错了什么.

我已使用Google Chrome成功下载了其中一个组件(https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/main/0.13.13/jars/main.jar),并且没有注意到它报告任何HTTPS证书错误.

这是Parallels of Ubuntu 16.04中的全新安装.

完整输出如下：

最佳答案 在遇到这个问题后,我自己在Ubuntu上安装了sbt,我找到了解决方案.我相信我们有同样的错误,所以这应该解决它.我从头到尾提供了在Ubuntu上下载和安装sbt的步骤.如果您只想修复错误,请从步骤4开始.

在终端中键入以下命令.请注意,如果转到www.scala-sbt.org/download.html,则可以找到这些命令.

echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudo apt-get update
sudo apt-get install sbt

2)现在在终端中键入sbt,它应该安装一些.jar文件并给你一个REPL(‘>’符号).

2.1)如果这样做,请在’>’后输入控制台签字并按下输入

2.2)现在提示符将显示为“scala>”.键入3 3,然后按Enter键以测试它.

如果在输入sbt后出现错误,请继续.如果你没有错误,恭喜你！你安装了Scala和sbt！

3)如果在步骤2中键入sbt产生类似于下图的错误,则转到步骤4.

4)您需要将默认JDK版本更改为8,如此处的堆栈溢出答案Exception on download: sun.security.validator.ValidatorException: No trusted certificate found所述

4.1)要执行此操作,请键入sudo update-alternatives –config java

4.2)在路径中选择带有java-8的选项.

注意：如果路径中没有java-8选项,则应该能够下载JDK8,然后返回步骤4.1将其设置为默认JDK.

5)然后再次运行sbt,它应该工作！
